摘要：Densities, viscosities and electrical conductivities of ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate ([C(4)mim][PF6]) in monoethanolamine (MEA) and N, N-dimethylethanolamine (DMEA) have been determined from (288.15 to 323.15) K. The results show that the densities of both binary mixtures linearly decrease with increasing temperature. The dependence of temperature on the viscosity has been fitted to the Arrhenius equation with high precision. A viscosity model based on the equation of state for chain-like fluids and a solute aggregation model were used to calculate the viscosity of binary mixture. The dependence of temperature on the electrical conductivity has also been fitted in the form of Arrhenius equation. The effect of concentration of ionic liquid on the electrical conductivity has been examined using the Walden rule. Excess molar volumes and viscosity deviations from a mole fraction average have been obtained and fitted to the Redlich-Kister equation. (C) 2008 Published by Elsevier B.V.
